Tolerance to high soil [Na(+)] involves processes in many different parts of the plant, and is manifested in a wide range of specializations at disparate levels of organization, such as gross morphology, membrane transport, biochemistry and gene transcription. Multiple adaptations to high [Na(+)] operate concurrently within a particular plant, and mechanisms of tolerance show large taxonomic ...

The findings, published in Nature Communications on August 29, 2019, could lead to the development of crop species that produce higher yields in soils with excess iron. The GSNOR gene is required for high iron tolerance throughout plants. Iron toxicity leads to impaired leaf and root growth. Plants ( Arabidopsis thaliana) with the functional ...

1. Different plant species show considerable variation in their selenium content. Primary indicators, also termed selenium accumulators, many of which are members of the genus Astragalus, are highly tolerant of selenium; they are known to contain tissue levels of several thousand µg selenium/g.Secondary indicators, tolerant to low concentrations of the element, may absorb up to 1000 µg ...

Bacteria-Mediated Drought Tolerance. Mutualistic associations between plants and bacterial communities in the soil are very common (Naylor and Coleman-Derr, 2018) and involve rhizobacteria, bacteria present in the rhizosphere (soils in close enough proximity to the root to be influenced by root exudate release), and bacterial endophytes in the root interior (Berg et al., 2014).
